Superseded by 2026.11.4. This release's ISO was made with a host makefs built at the previous Userland pin, so its tag rebuilds another ISO; its .img and the sets are reproducible. 2026.11.4 installs the same system.

The fourth EmiBSD release for arm64, signed, again a pre-release: the install media install
EmiBSD in QEMU, the installer verifies the sets against the medium's signature, and the
installed system boots to login:. It has not yet been compared with a real OpenBSD
(diff-openbsd, step 5 of the checklist).

Not for production. EmiBSD is an experiment. It runs only in QEMU, and its crypto,
network and storage code is unaudited.

What changed since 2026.11.2

  • Kernel 20261108-b99aedaf: the mbuf (N6.1) and the socket layer (N6.2a: sockets, socket
    buffers, domains, protocols, UNIX domain sockets with descriptor passing) are the new
    kernel's, with the inherited code's call sites as adapters over them; the 19 socket system
    calls are native (N6.2b), and the boot line reads abi: 331 syscalls, 189 native. A wg(4)
    ordering fix. Built with DevTools llvm-23.1.4+emibsd.2.
  • Userland 2026.11.4: /usr/include takes the kernel ABI's headers from the Kernel
    release; the build checks every system call against the kernel's MANUAL.toml; the manual
    leaves out what this kernel lacks (section 9, the pages of absent system calls and of devices
    the kernel does not configure, other architectures' man4, config(8)).
  • The mirror lists its directories: https://cdn.emibsd.org/ can be browsed down to the
    sets like a web server's listing, and each set directory has the index.txt the installer
    reads. This release's tree is on https://cdn.emibsd.org/pub/EmiBSD/8.0/arm64/ and kept as
    pub/EmiBSD/releases/2026.11.3/arm64/.

The media

  • emibsd-2026.11.3-arm64-install.iso: for QEMU and VMs; cd9660 with an EFI El Torito image.
  • emibsd-2026.11.3-arm64-install.img: a USB stick image, laid out as OpenBSD's arm64 install80.img.
  • SHA256 and SHA256.sig: the sums of both, and their signature with emibsd-80-base
    (keys/emibsd-80-base.pub,
    RWR7BZgzESUf6vppLWNF/Q83e1OvjRIDJ4kNBtzh0gPMW889JsfGSjU3).

Both carry the sets, so the install needs no network. How to run it in QEMU, step by step:

What it assembles

Pin
Kernel pre-release 20261108-b99aedaf: bsd.mp and bsd.RAMDISK, with the ABI linked in; BOOTAA64.EFI
Userland release 2026.11.4, signed: the base80, comp80, game80 and man80 sets (.tar.zst), miniroot80.fs, INSTALL.arm64
DevTools 832bb279392f, llvm-23.1.4+emibsd.2; Rust 1.99.1+emibsd.1
OpenBSD 3ce1f3f79392, the pin Kernel, Userland and LandingZone share

Checked

  • just check, just fetch, just smoke: the pins exist and match their sums, Userland's
    signature verifies, the released kernel boots.
  • just media twice from the manifest commit: the same images and the same SHA256.sig.
  • just smoke-media: each image installs all four sets onto a fresh disk in QEMU virt
    (EDK2, cortex-a72), the installer reports Signature Verified, and the installed disk boots
    alone to login:; uname -a gives EmiBSD emibsd.my.domain 8.0 GENERIC#1900 arm64
    (ISO: install 157 s, boot 49 s; stick: install 105 s, boot 47 s).

Known gaps

  • No diff-openbsd yet: the installed system has not been compared with a real OpenBSD.
  • The kernel's network smokes run at Kernel's N6 close; this kernel has not been through it.
  • The comp set has no cc, ld or ar yet (Userland's comp, with DevTools' native
    toolchain, T3b), so reorder_libs and the ssh-agent relink fail at boot, without harm.
  • reorder_kernel fails at boot without a kernel.tgz (Kernel's and Userland's), without harm.
  • Network installs and sysupgrade from the mirror are untested; the media install from local sets.
  • ISO installs print newfs_msdos: /dev/r0000000000000000.i: No such file or directory
    during disk setup: OpenBSD 8.0 prints the same line with a CD attached; the install is not affected.
  • Tested only in QEMU's virt machine; real hardware is untried.
  • arm64 only; amd64 waits for Kernel's N10.
